Colcannon is full of flavor. If you like mashed potatoes, you’ll most likely love this dish. The mashed potatoes get tons of flavor from the green onions and a nice texture from the chopped kale. We all love butter and milk in our potatoes, so that is also in this colcannon recipe with salt and pepper to taste!

Colcannon makes a beautiful presentation. We like to serve it warm in a large dish with a pat of butter right on top. We’re all about adding greens to your favorite dishes over at Know Your Produce.

What is Colcannon?

Colcannon is a traditional Irish mashed potato recipe with kale or cabbage. It’s a great way to get your veggies in for kids who love potatoes but may not eat kale by the spoonful. Cabbage is also a great addition and you want you could even do both.

The next time you see kale at your grocery store why not pick it up and give colcannon potatoes a try? This recipe would be perfect with your Irish favorites on St Patrick’s Day, or any day you want to have delicious side dish for your family.

There are a few options to add the green onions and kale into your mashed potatoes. You can cook the green onions and kale with the butter and milk that’s getting warmed up for the potatoes, or you can place them in the boiling water for about 1 minute. We like to go with the butter and milk method so all the nutrients stay in the mixture whereas if you blanch in the water, once you drain, there can be some nutrient loss.

Could you use spinach in this recipe?

You could, but spinach wilts immediately upon heat so you won’t need to wilt them separately.


This with your Colcannon mashed potatoes?! WOWZA! Pass the napkins, please!

Although I have never had Colcanno, I think it would be delicious with cabbage and any type of onion. I am not a fan of kale but I am willing to try it. Does it still have a strong taste in the potatoes?

It’s pretty mild.

I love Colcannon. I make mine with cabbage and leeks. Yours sounds wonderful.
